(Phys.org)—An interdisciplinary effort at the Friedrich Miescher Institute for Biomedical Research (FMI) addressed the question of how mRNA content, which is translated into proteins, is regulated in the cell. Supported ...

(Phys.org)—The sorcerer's apprentice started a water-carrying system, but couldn't stop it, and soon he was up to his neck in water, and trouble. Living cells have a better design: When they activate a gene, they have a ...

(Phys.org)—It's not just a few key genes and proteins that cycle on and off in humans in a 24-hour circadian pattern as the sun rises and falls. Thousands of genes in organs throughout the body show predictable daily fluctuations, ...

When an invading bacterium or virus starts rummaging through the contents of a cell nucleus, using proteins like tiny hands to rearrange the host's DNA strands, it can alter the host's biological course. The invading proteins ...

The first step in gene expression is the exact copying of a segment of DNA by the enzyme known as RNA polymerase II, or pol II, into a mirror image RNA. Scientists recognize that pol II does not transcribe RNA via a smooth ...

Transcription factor proteins essentially act as genetic on/off switches, binding specific stretches of DNA that enable them to stimulate or repress the activity of neighboring genes. However, it remains a challenge to authoritatively ...

A Rice University researcher and his colleagues have received a National Institutes of Health grant to see how delays in gene transcription  life's most basic messaging system  affect cellular processes.

For about a dozen years, synthetic biologists have been working on ways to design genetic circuits to perform novel functions such as manufacturing new drugs, producing fuel or even programming the suicide of cancer cells.

Planarian flatworms have come under intense study for their renowned ability to regenerate any missing body part, even as adults. But now they may take on a starring role as a model system for studying eye development and ...
